SUPERNAIT 2
4 SUPERNAIT 2 Introduction, Installation and Connection
The Supernait 2 is a very high performance stereo integrated amplifier that combines a
preamplifier providing six line-level analogue inputs with a power amplifier rated at 80
Watts per channel. The Supernait 2 can be controlled by either its remote handset or by
front panel mounted volume and balance knobs, and mute and input selection buttons.
The Supernait 2 remote handset is described in Section 18 of this manual. A front panel
6.3mm jack socket enables the use of headphones with the Supernait 2.
A variety of power supply upgrade, alternative preamplifier and alternative or additional
power amplifier options are possible for the Supernait 2. Diagrams illustrating the
connection of some of these are shown in Section 6. If no power supply or alternative
amplifier options are to be employed, the Supernait 2 preamp/power amp link plug,
supplied in the accessory pack, must be fitted to the rear panel “preamp out” and
“power amp in” sockets. The link plug is shown fitted in Diagram 5.2.
Your Supernait 2 should be installed on a dedicated equipment stand intended for
the purpose. Do not stand it directly on top of another item of equipment. Care should
be taken to ensure that it is level. The amplifier should be installed in its final location
before connecting cables or switching on. Ensure that the volume is turned down before
switching on.
4.1 Mains Power Connection
Connect the Supernait 2 to a mains power socket using
either the mains cable supplied or a Naim Power-Line.
4.2 Signal Inputs
The Supernait 2 front panel input buttons select the source
input signal to be routed to the integral power amplifier
and the loudspeakers or headphones. The six buttons are
labelled
cd
,
tuner
,
hdd
(hard disk drive),
av
,
aux 1
and
aux 2
.
The
cd
,
tuner
,
hdd
and
av
input buttons correspond to
parallel DIN and RCA phono input sockets on the rear
panel, while the
aux 1
input button corresponds only to a
pair of RCA phono sockets.
Note:
The hdd and av sockets carry both inputs and
outputs. See Section 4.4 for more information.
The
aux 2
input button corresponds to a DIN input socket
on the rear panel. The
aux 2
DIN socket also carries a
power supply output intended to power a Naim
Stageline
or
SuperLine
phono preamplifier.
Note:
For optimum sound quality DIN sockets should be
used in preference to RCA phono sockets.
Note:
Where an input has DIN and phono socket options
only one should be connected at any one time.
Always use high quality interconnect cables to connect
sources to inputs. The Naim Hi-Line will produce the best
results.
4.3 Speaker Outputs
A set of stereo speaker connection sockets is provided on
the rear panel. Custom Naim loudspeaker connectors are
supplied to make the connection and in order to comply
with current European safety regulations these should
always be used. Naim speaker cable will provide the best
results, however, a wide range of speaker cable types can
be used without risk of damage to the amplifier.
Ensure when connecting speakers that they are “in
phase”. That is, the positive and negative connection
orientation at both the speaker and amplifier ends of the
cable is the same for both channels.
4.4 av and hdd Outputs
The Supernait 2
av
and
hdd
inputs have associated
outputs that enable the selected input signal to be routed
externally; to an audio recording component for example.
Note:
The av and hdd outputs remain active while
their corresponding inputs are selected. Take care that
a feedback loop is not inadvertently created by the
simultaneous selection of input and output.
4.5 Headphone Output
The Supernait 2 headphone output is able to drive the
majority of headphone types. The 6.3mm (1/4”) jack
socket, rather than the smaller 3.5mm jack socket, provides
more reliable connection and potentially higher sound
quality. Most high-quality headphones are supplied with
an adaptor that enables use with either 3.5mm or 6.3mm
jack sockets. Inserting a headphone plug will mute the
Supernait 2 speaker outputs. Removing the headphone
plug will restore the outputs.
Note: The Supernait 2
incorporates an AV
Bypass switch on its rear
panel. The switch should
only be set to “On” if the
amplifier is to be used
in conjunction with an
AV processor in a home
theatre system. In all
other installations the
AV Bypass switch should
be set to “Off”. Speaker
and amplifier damage
may occur if a signal is
inadvertently connected
to the Supernait 2 av
input while the AV
Bypass switch is “On”.
